WIRE-BENDING MACHINE.

Specification of Letters Patent.

Patented Sept. 5, 1905.

To all whom, it may concern.-

Be it known that we, RAYMOND E. ACKLEY, a resident of Rockford, in thecounty of \Vinnebago, and ALBERT E. IIIX, a resident of Kingston, in thecounty of Dekalb, State of Illinois, citizens of the United States, havemade a certain new and useful Invention in \Vire-Bending Machines; andwe declare the following to be a full,clear, and exact description ofthe same, such as will enable others skilled in the art to which itappertains to make and use the invention, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

Figures 1, 2, 3, and L are perspective views of my invention with partsin four positions assumed in hendingthe link-eye in form. Fig. 5 is aperspective View of the rod It, &c., removed from the tubular guide andin the position shown in Fig. a. Fig. 6 is a perspective view of thetubular guide. Fig. 7 is a section on the line T T, Fig. 6.

The invention has relation to machines for making interlocking rings orloops upon wires or strips of pliable metal; and it consists in thenovel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the letter adesignates a frame to which is secured a tubular guide Z), having anaxial extension 0. At the side of the upper end or commencement of theextension 0 is located a stop or gage (I. The axial extension 0 isformed with an opening 0, extending longitudinally, and such openinghounded by a spiral]y-extending margin j, which is connected with theinterior tubular bending-surface of the extension by a rounded surface,as at g.

Engaging the tubular guide 7) is a rod it, which is designed to havemotion of reciprocation through said tubular guide and its axialextension. This rod is made with a continuation or mandrel 7.; ofsmaller diameter, such mandrel joining the rod at its shoulder m, whichis annular. The mandrel or continuation Z- is provided with a cam end p,having a flattened guide-face 11, whereby the wire or strip to be bentis guided transversely to the gage. The flattened cam end 7) joins themandrel l' at a terminal shoulder a. The mandrel is provided with alongitudinal notch or recess .2, sunk into its peripheral surface.

\Vhen the rod 71 is pushed through the tubular guide 7) sufliciently tobring the guideface a of the cam end 7) opposite the gage, the end of apliable wire or strip t is passed transversely until it touches thegage. The rod is then turned half around and is given motion ofreciprocation. The annular-shoulder '11 engages the bent portion of thewire or strip, and the latter is carried downward along the interior ofthe tubular forming or bending extension 0 in such wise that the end ofthe wire or strip is by means of the spiral margin or cam edge of theopening 1 partially bent around the mandrel I of said rod. The loop oreye of another wire or strip (indi cated at '10) now being pressed intothe notch of the mandrel, the downward movement of the rod is continueduntil the end of the tubular extension of the guide is reached, when thework will be discharged and the eye of the first-mentioned wire or stripwill be found completely formed and interlocked with that of the wire orstrip last referred to.

In the operation above described it is apparent that the initial bend ofthe wire is made by rotation of the cam end of the mandrel, which makesa bend in the wire, whereby it is enabled to engage the mandrel Z andthe annular shoulder 11/. Thereafter the work is performed byreciprocation of the rod through the operation of the notched mandreland the spiral cam of the tubular extension 0.

Having thus described our invention, what we claim, and desire to secureby Letters Patcut, is-

1. In a device for bending wire, the combination with a shouldered andnotched mandrel, of a gage, and a tubular guide having an axialextension provided with a longitudinal opening having a spiralcam-margin, substantially as specified.

2. In a device for bending wire, the combination With a mandrel having anotched In testimony whereof We aflix our signashoulder, of a gage orstop, a tubular guide tures in presence of two Witnesses.
